DETAILED DESCRIPTION

As used herein, “mobile device,” “portable electronic device,” and“handheld electronic device” (i.e., handheld device) may refer tovarious types of portable processor-based devices, including but notlimited to: notebook computers, digital assistants (e.g., personaldigital assistants or ‘PDAs’), media players (e.g., MP3 players), mobiletelephones, smart phones, mobile game players, digital cameras, portablerecorders, tablet computers, portable e-ink readers, all-in-one portablecomputers, and/or portable television/s, etc.

As discussed above, conventional device covers provide a protectivebarrier between an external surface of the enclosed electronic deviceand the surrounding environment. In some instances, conventional devicecovers utilize protective films or plastic wrappers, for example, toprovide protection to a display, or provide matting or anti-glarefeatures. Conventional device covers may also provide plugs or coveringfor device inputs (e.g., touch-displays, actuatable buttons, or scrollwheels, etc.). However, such conventional device covers provide littlebeyond physical protection of the enclosed host device. For example,conventional covers do nothing to expand the mechanical utility and/orelectrical functionality of the enclosed device.

Aspects of the subject technology address the above limitations byproviding device covers and accessories that expand devicefunctionality.

Cover/Attach Cover/Mechanical Cover:

In some aspects, the present disclosure relates to a cover (e.g., “aprotective cover,” “a back cover,” “mechanical cover,” “a handheldelectronic device cover,” “attach cover,” or “device cover”) configuredto facilitate the attachment of various accessories. Attachableaccessories (e.g., “accessory device,” “accessories,” “deviceaccessories,” “attachment accessory,” or “accessory attachments”) may beused to expand the utility of the corresponding mobile device. The covermay include a surface (e.g., an accessory attachment area) on which thevarious device accessories may be coupled. The accessory attachment areamay include an arrangement of connection points (e.g., catch receiversor receivers) that facilitate the mechanical coupling of the cover withvarious accessories. Although the number and configuration ofaccessories may vary, the cover may be configured to support theattachment of a single accessory, or the simultaneous attachment of twoor more accessories.

It is understood that the cover may be constructed of various materials,or a combination of materials, including but not limited to: plastics,thermoplastics, thermoplastic polyurethane (TPU), polycarbonate,polyvinyl carbonate (PVC), and/or silicon, etc. The cover may be formedfrom a variety of materials including, for example, but not limited tosoft, hard, rigid, flexible, compliant, etc. Some examples of materialtypes include but are not limited to paper, plastic, metal, rubber,silicone, fabric, foams, leather, ceramics, films, and the like. Thematerial generally depends on the desired needs of the outer covering.It should be appreciated that the outer covering is not limited to asingle material and may include a combination of materials. The exactcombination may depend on the needs of the outer covering. Examples oftrade-offs include rigid/flexible, soft/hard, soft1/soft2,plastic/metal, silicon/plastic, etc. In one particular embodiment, theouter covering is formed from flexible and/or compliant materials suchas rubber, silicone, fabrics (e.g., neoprene), and various films.Additionally, the cover may be constructed as a contiguous structure, ormay function as a coupling of two or more separate but attachableportions. As discussed in further detail below, the cover may alsoinclude one or more layers, for example, that are fitted together toform one or more receivers, including a space recessed into the coverbody, and that is configured to receive at least one projectionassociated with attaching an accessory.

In some aspects discussed herein, the cover is configured to enclose anassociated handheld device (e.g., a smartphone) through the abutment ofone or more edges of the cover with one or more edges of the encloseddevice. However, it is understood that other coupling methods may beemployed without departing from the scope of the subject technology. Forexample, a cover may be coupled to or around an electronic devicethrough the use of friction coupling, i.e., whereby contact one or morecover surfaces create a frictional interference with one or moresurfaces of the respective device. The contact may be a point, line orarea contact so that the cover is coupled with the electronic device.

Accessory/Mechanical Accessories/Mechanical Device Accessories:

Aspects of the technology also relate to an accessory with a securementdevice for coupling an accessory to the cover. The securement device maybe a plurality of projections. In some aspects, the device accessory isfastened to the securement device. In turn, coupling the accessory tothe cover is accomplished by attaching the securement device with thecover, e.g., using one or more elongate projections as securement deviceconfigured for insertion into a respective receiver in the cover. Insome aspects, mating of a projection into a respective receiver (i.e., aspace of a receiver) may be controlled using a release button of thesecurement device.

As discussed in further detail below, various device accessories (e.g.,a “kickstand,” “bike mount,” or “selfie-stick,” etc.), may be attachedto the cover to expand device utility, for example, by securing thedevice to various surfaces, and/or by appending useful devices.

Cover/Electrical Cover/Electrical Attach Cover:

Other aspects of the technology relate to a cover that may be anelectrical cover (e.g., “electrical cover,” “attachable electricalcover,”) configured to facilitate a transfer of power and/or databetween an enclosed device and one or more accessories. The electricalcover may include a cover body configured for securement to anelectronic device (e.g., an electronic accessory), as well as anelectrical connector configured for coupling with a power port of thehost electronic device.

Depending on implementation, the electrical connector may be a flexiblewire or bus that may be plugged into a power/data port of the hostdevice, such as a Universal Serial Bus (USB) port. Alternatively theelectrical connector may include a rigid plug that is integrated intothe cover body and configured for insertion into the power/data port,for example, upon securement of the cover to the host device.

As discussed in further detail below, the electrical attach cover isconfigured to facilitate power transfer between an electronic deviceenclosed by the electrical attach cover, and a device accessory, thuspermitting a communicative coupling with a variety of electronic deviceaccessories, including but not limited to: batteries, various datastorage device/s, and/or wireless radios, etc.

Accessories/Electrical Accessories/Electrical Device Accessories:

Some aspects of the technology relate to accessories/electricalaccessories/electrical device accessories configured for expanding theelectronic and/or information processing capabilities of a host deviceenclosed by the cover. Depending on the desired implementation, theelectrical accessories may be electrically and mechanically coupled withthe cover, e.g., via electrical contacts disposed on one or more of theprojections.

As discussed in further detail below, electrical device/accessories mayinclude one or more power storage devices, memory devices, USBcommunication devices and/or wireless communication devices, such asBluetooth® radios, WiFi, Wi-Fi direct devices, etc.

Asdepicted, the mobile device 102 is at least partially enclosed by thecover 106, as well as including accessory attachment (not shown) tofacilitate coupling with the bicycle handlebar 104.

FIG. 1B shows a back (or rear) isometric view of the cover 106 having ahandlebar attachment accessory 108. As illustrated, the back side of thecover 106 is a surface of the cover 106 that is opposite to an insidesurface (not shown) of the cover that would contact the enclosedelectronic device.

The handlebar attachment accessory 108 may have a strap receiving slot110 configured to receive a strap disposed around the handlebars 104 orany other tubular member. In some aspects, the handlebar attachmentaccessory 108 may also have a concave or contoured surface 112, forexample, to facilitate a secure engagement with a tubular member, suchas the handlebars 104.

The cover 106 (shown in FIG. 2 as the cover body 200), provides anaccessory attachment area 114 providing coupling with one or moreaccessories. As may be appreciated in FIGS. 1A and 1B, the cover 106 maybe coupled with various accessories, such as a mount for receiving thebicycle handlebar 104, thereby securing the mobile device 102 to thebicycle handlebar 104.

While the illustrated embodiment is drawn to the bicycle handlebar 104,it is within the scope of this disclosure for the cover 106 to bemounted to other objects or surfaces including, but not limited to:motor vehicles (e.g., a vehicle dash, vehicle windshield), clothing oraccessories (e.g., a backpack, shoulder strap), surfboards, arm bands,carabineers, attachment of a stylus or pen, etc.

The cover 106 may be configured to cover a portion of one or moreexternal surfaces of the mobile device 102 for ornamental and/orprotective purposes. Additionally, the cover 106 can be configured toact as an electronic accessory to the mobile device 102, i.e., asupplementary system that improves the functional capabilities of themobile device 102. In most cases, the cover 106 is a distinct element,which is not part of the originally designed mobile device 102. Instead,the cover 106 is an add-on or an accoutrement of the mobile device 102.The cover 106 may be configured to help protect the mobile device 102(i.e., it may serve as an armor or shock protection that helps preventstructural and/or surface damage to the mobile device 102). Additionallyor alternatively, the cover 106 may provide ornamentation to the mobiledevice 102 (i.e., it may help define the overall ornamental appearanceof the electronic device). The cover 106 can also permit personalizedornamentation. The cover 106 may also provide tactility in order toimprove the feel and grip to the mobile device 102.

The cover 106 can at least partially conforms to the outer shape of themobile device 102. For example, by providing an internal shape/innersurface and/or being flexible enough to follow the contour of the mobiledevice 102. The external shape of the outer covering may be widelyvaried. It may be designed for ornamental, protection, and/or ergonomicreasons. Generally, however, it tends to follow the general shape of themobile device 102.

The cover 106 may for example be laid, set, wrapped, spread upon, aboutor over a portion of the mobile device 102. The mobile device 102 mayinclude a front cover and a back cover defining the front and backsurfaces, respectively, of mobile device 102. The front cover may have adisplay for displaying image and the back side is a side that is facingdifferent direction than the front side with the display. The front andback cover may toward opposite or different direction. The cover 106 maybe configured to cover a surface of the mobile device 102 including aportion of a single side, multiple sides, and/or all sides of the mobiledevice 102. For example, the cover 106 may be a film/layer/cover that isapplied to a single surface of the mobile device 102 (e.g., a portion orall of the back side).

The cover 106 may also be a flexible covering that includes a cavity forreceiving the mobile device 102 or a flexible covering thatwraps/stretches around some portion of the mobile device 102. The outercovering may be referred to (among others) as a case, shield, container,jacket, vest, skin, protector, and the like of the mobile device 102.

The cover 106 generally includes a body or member that couples to themobile device 102. The body or member may also be removable ordetachable from the mobile device 102. The body or member 202 may becarried by the mobile device 102, but is not part of the mobile device102. The configuration of the body or member may be widely varied, butis typically configured to cover the outer surface(s) of the mobiledevice 102. The body or member 202 may be universal in its application(not specific to a particular device) or it may be dedicated to aparticular device. In either case, the body or member can be configuredto follow the outer contour or shape of the surfaces of the mobiledevice 102. In one example, the body or member forms a surface layerthat attaches to the outer surface of the mobile device 102. In anotherexample, the body or member forms an enclosure that includes surfaces(e.g., walls) that surround the outer surfaces of the mobile device 102.

The cover 106 may be adhered to or around the mobile device 102 using avariety of techniques including but not limited to: adhesive, friction,static, elasticity, suction, fasteners, snaps, connectors, and the like.In some examples, the cover 106 forms an enclosure that includes a void,cavity, opening, pocket or compartment for receiving a mobile device 102therein (i.e., the mobile device 102 can be placed into the void). Inanother example, the cover 106 may be press fit onto the mobile device102. In yet other examples, the cover 106 is a surface (e.g., platform,film) that is attached to a surface of the mobile device 102 (e.g.,adhesive backed surface or surface with static electricity properties ora surface with suction cups). In yet other examples, the cover 106 isstretched around the mobile device 102 (e.g., the outer covering isflexible and conforms to the outer shape of the mobile device 102). Inother examples, the cover 106 may trap or surround the mobile device 102between multiple sections (i.e., lower and upper half). In accordancewith one embodiment, the cover 106 may be formed from a soft, flexibleand/or compliant material that can be wrapped around the varioussurfaces of the mobile device 102. For example, the material may allowthe covering to stretch over the mobile device 102 (e.g., form fitting).By way of example, the cover 106 may be formed from a stretchablematerial that includes a small opening that can be stretched toaccommodate the larger mobile device 102 as it is inserted into thecover's 106 outer covering.

Once the mobile device 102 is inserted, the material conforms to theshape of the mobile device 102, which provides a tight fit around thesurfaces of the mobile device 102. The cover 106 may, for example,surround multiple side surfaces if not all of the side surfaces of themobile device 102. In one particular example, the material may besilicone. These types of coverings are sometimes referred to as “skins”as they create a new outer layer analogous to skin.

FIGS. 2 and 3 show a cover body 200 including a plurality of receivers202 disposed on an accessory attachment area 204. The accessoryattachment area 204 may be an outer back surface of the cover body 200.The receivers 202 may be arranged in a matrix (or lattice configuration)of rows and columns, wherein each of the individual receivers areseparated in a regular spacing pattern. The receivers 202 may also beconfigured in a random distribution, or an isle or artwork. As discussedin further detail below, each receiver of a plurality receivers 202 mayreceive a projection (shown in FIGS. 5, 11, and 12), thereby couplingthe cover body 200 with a device accessory. The cover body may comprisea base and at least one sidewall extending away from the base, the atleast one sidewall being shaped to substantially conform to a handheldelectronic device and the at least one sidewall comprising theattachment area with the plurality of receivers. The receivers may bearranged in 2 dimensional lattice such as bravais lattice, rhombiclattice, hexagonal lattice, parallelogrammic lattice or rectangularlattice. As for the shape of the receiver, the shape may be square,circular, rectangular, honey comb, or any kind of polygon.

It is appreciated that receivers 202 on the cover body 200 may bearranged in other patterns (e.g., not a matrix or lattice pattern). Forexample, the receivers 202 may be irregularly spaced, without departingfrom the scope of the subject technology.

FIG. 4 illustrates an example of a mounted device cover 400. In theimplementation of FIG. 4, a cover body 200 is mounted to support 404 viaan adjustable mount 402. The adjustable mount 402 may be coupled withthe cover body 200 with one or more projections engaged with one or morereceivers 202 disposed on an accessory attachment area 204.

The mounted device cover 400 may allow 360-degree movement of the coverbody 200 relative to support 404 via the adjustable mount 402. Theadjustable mount 402 allows a user to adjust the positioning of thecover body 200 to a preferred orientation.

FIG. 5 shows an exploded view of a cover 500 configured to couple with akickstand accessory 504. The cover 500 includes a cover body 200configurable with the kickstand accessory 504. The kickstand accessory504 includes at least one projection 502 configured to be received inone or more receiver 202. The kickstand may have a first end and asecond end. The plurality of projections 502 is placed on the first endfor attaching the kickstand on the cover 200. The second end may beextended away from the cover 200 to form a supporting structure via theplurality of receivers and the plurality of projections for the handheldelectronic device and the cover 200. The kickstand accessory 504 may becoupled at any desired orientation to support the cover 500 in aportrait position, a landscape position, or any position therebetween.

FIG. 6 shows an assembled view of a cover 500 coupled with the kickstandaccessory 504. A projection 502 is received in one of receivers 202 onan accessory attachment area 204 of a cover body 200. The kickstandaccessory 504 may be transitioned to extend away from the cover body 200(as shown) and support the cover 500, or be transitioned substantiallyflush against the cover body 200 (as shown in FIG. 5). The kickstandaccessory 504 may be substantially flush against the cover body 200 whennot in use to reduce the profile of the cover 500. As used herein,‘substantially flush’ may refer to a configuration whereby the kickstandaccessory 504 is positioned adjacent to the accessory along the entiretyof a contacting surface of the kickstand accessory 504.

FIG. 7 shows an isometric view of a handheld electronic device 700having flip cover 702. The flip cover 702 has a cover portion and acoupling portion. The cover portion of the flip cover 702 as showed inthe FIG. 7 with arrow showing 702 covers at least a portion of the frontsurface of an electronic device, such as a surface of the electronicdevice that includes a display. The coupling portion as showed in theFIG. 8 with the arrow showing 702 is coupled to the cover via thereceivers 202 on the cover body 200. The flip cover 702 may betransparent or semitransparent so that information such as time, batterylife, incoming call information, music information, camera interface maybe projected through the flip cover 702. The flip cover 702 may have oneor more apertures 704 therein to provide access to predetermined screenfeatures, such as time, battery life, incoming call information, etc. Inat least one embodiment, an apertures 704 formed in the flip cover 702include a clear viewing surface such as glass, plastic, acrylic, or thelike.

FIG. 8 shows a rear isometric view of a handheld electronic device 700having a flip cover 702. In the illustration of FIG. 8 the flip cover702 also covers a portion of a back surface of the electronic device,e.g., a surface that is opposite the front surface containing thedisplay, as indicated above with respect to FIG. 7. The flip cover 702may be coupled with the cover body 200 via the coupling portion and thereceivers around an edge of the cover body 200.

FIG. 9 shows an interior view of a cover body 200. The cover body 200has receivers 202 formed therein. The receivers 202 may be formed in amatrix of rows and columns (e.g., a lattice pattern) allowing adevice/accessories to be coupled with the cover body 200 at one or morelocations, positions, and/or orientations. While a lattice pattern isshown, any pattern or even a random distribution of receivers 202 mayalso be applied.

FIG. 10 shows a detailed view of one of the receivers 202. The receiver1002 may have a space recessed into a cover body that is bounded, atleast partially, by a recess wall 1004. The receiver 1002 includes anengagement surface 1006 configured for forming an abutting engagementwith a projection associated with an accessory (e.g., kickstandaccessory 504). While a circular receiver 1002 shape is shown in FIG.10, the shape of the receiver 1002 may be square, rectangle, triangle,octagon, irregular, and so forth. The particular shape of the receiver1002 may vary. The receiver may be a through hole, blind hole, interruptholes, taper hole, taper holes with different taper angles at differentsection of the receiver. The arrangement of the receivers may becombination of the different type of holes.

FIG. 11 shows example an environment 1100 illustrating an engagementbetween a projection 1104 and a receiver 1110. As illustrated, thereceiver 1110 is formed by a space recessed into the cover body that isbounded, at least partially, by a recess wall that includes anengagement surface 1108. In the illustrated example, the projection 1104includes elongate mechanisms or member 1102 and protrusions 1106.Correspondingly, the receiver 1110 includes an engagement surface 1108configured for abutting engagement with each protrusions 1106. Thereceiver may have a first end and a second end formed by the recesswall. The first end and second end may be shaped differently for bettersecurement of the projection into the receiver. The aperture or openingof the first end may be smaller than the aperture or opening of thesecond end as showed in FIG. 11. When the projection 1104 is pressedthrough, coupled or engaged to the receiver 1110, the elongatemechanisms is compressed through the first end. As the projection ispressed to reach the second end which having a bigger aperture or largerdiameter than the first end, the elongate mechanism may be recovered ordecompressed to couple to the receiver 1110. The engagement surface 1108and the recess wall may face a different direction. The protrusion 1106is locked, coupled, or contacted with the engagement surface 1108 sothat the protrusion is securely placed in the receiver. The contact maybe a point, line or area contact so that the protrusion is securelycoupled with the receiver.

As discussed above, the receivers (e.g., receiver 1110) may be disposedin a cover body in various locations or arrangements. In some aspects,the receiver is configured such that an inserted projection (e.g.,projection 1104) extends away from a back-side of the cover body, e.g.,wherein the back-side is opposite an interior cover surface of thecover. As further illustrated in the example environment 1100, theengagement surface (e.g., engagement surface 1108) may be configured toprovide a surface that faces in a direction different from a surfacedefining the recess wall. By way of example, the engagement surface 1108may face or substantially face toward a direction of an enclosedelectronic device (not illustrated in FIG. 11).

FIG. 12A shows a detailed view of a plurality of projections receivedwithin a plurality of receivers (receiver 1204, receiver 1206, receiver1208, and receiver 1210). The cover body section 1200 may accommodatevarious receivers engaged with a projection. As may be appreciated inthe cross section of the receiver 1210 receiving the projection 1104,the engagement surface 1108 is abutting engaged with the protrusion1106. The plurality of projections on the accessory may be arrangeddifferently in consideration of accessory securement. As an example ofthe arrangement of the plurality of projections, the projections in thereceivers 1210 and 1204 have the protrusions to securely coupled to thereceivers, whereas the projection in receiver 1206 lack the protrusionto lock on the receiver 1206. The additional projection without theprotrusion in the receiver 1206 may be used for security of a lateralmovement or an angular movement with other projection. As for theprojection with protrusion as in the receivers 1204 and 1210 may be usedfor limiting the lateral, angular, axial, or perpendicular movement. Thenumber of the projection with protrusion may be configured to fit theease of the attachment or detachment. As the number of the projectionswith protrusions increases, it is expected that the accessary is moresecure on the cover. The placement of the projections may be aconsideration, too. As shown in FIG. 12A, the receiver 1208 does nothave a corresponding projection from the accessory to be inserted into.The projection may be placed on the accessory to accommodate the weightdistribution of the accessory or the security requirement.

In some aspects, the number of the projections on the accessory may beless than the number of receivers on the cover. In other words, thenumber of receivers is more than the number of projections so that theaccessory may be moved from a different location on the cover or havinga second accessory attached to the cover at the same time. The accessorymay attach to a different location or an orientation on the cover byusing the same projection on the accessory to different receivers on thecover. For example, as shown in FIG. 12B the accessory may be moved froma first position to a second position by attaching a first set ofreceivers 1210 at the first position and attaching a second set ofreceivers 1211 at the second position. The first set of receivers 1210is different from the second set of receivers 1211 by at least onereceiver 1212. As the accessory moves further away from an originalposition, the first set of receivers used for attaching the cover andaccessory has more different receivers used. There may be a secondaccessory attached to the cover. The first accessory may attach to afirst side of the cover and the second accessory may attach to a secondside of the cover using a different set of receivers.

FIGS. 13-15 show various engagement arrangements for a matrix ofreceivers. The matrix of receivers 1300 may be secured to a cover with aprojection 1302 at four corners. As may be appreciated in FIG. 14, anadditional center projection 1402 may be employed in addition to theprojection 1302 at each of the four corners. As may be appreciated inFIG. 15, the remaining receivers of matrix of the receivers 1300 may besecured with the additional projections 1502. The shown arrangements aremerely illustrative, and it is within the scope of the disclosure toimplement any arrangement of the projections within matrix of thereceivers 1300.

FIGS. 16-20 show various projection embodiments. As may be appreciatedin FIG. 16, a projection 1600 is substantially circular and has aprotrusion 1602 extending around the circumference of the projection1600. As used herein, “substantially circular” may mean that theprojection 1600 may have a circular or semi-circular shape, such as anoval or oblong shape or any other shape. The shape of the projectionsmay correspond to the shape of the receivers on the cover. The shape ofthe protrusion 1602 may be different from the shape of the projection.The shape of the protrusion 1602 may correspond to the shape of theengagement surface mentioned above. As showed in FIG. 16, the shape ofthe projection 1600 is the same circular shape as that of the protrusion1602. It will be apparent to those of skill in the art that otherprojection geometries may be implemented, without departing from thescope of the technology. By way of example, any of the projectionsimplemented herein (e.g., projection 1600) may include symmetricalshapes (e.g., a square or rectangular shape), as well as non-symmetricalshapes.

As may be appreciated in FIG. 17, a projection 1700 may have an aperture1702 formed in the center. As may be appreciated in FIG. 18, aprojection 1800 may have two substantially equal portions 1804 eachhaving a protrusion 1806 extending from the circumference and the centeraperture 1802. The center aperture 1802 may allow displacement ofsubstantially equal portions 1804 during securing and releasing of theprojection with a receiver. As may be appreciated in FIG. 19, aprojection 1900 may have two substantially semicircular portions 1902and only one of two portions has a protrusion 1904 extending therefrom.As may be appreciated in FIG. 20, a projection 2000 may have threesubstantially equal portions 2004 each having a protrusion 2002extending therefrom.

FIG. 21 shows an example engagement 2100 of a projection 2102 disposedwithin a receiver 2104. The example engagement 2100 includes theprojection 2102 engaged in the receiver 2104. A protrusion 2106 of theprojection 2102 may engage the engagement surface 2108 of the receiver2104. The projection 2102 may be engaged with a receiver with adifferent opening at a different end or engaged with a through holereceiver. The projection 2102 is compressed through the receiver 2104and decompresses at the end of the receiver and engaged on the surfaceof the cover via an engagement surface 2108. The projection describedabove and below may be engaged to a different kind of receiver to forman engagement of the cover and the accessory.

FIG. 22 shows an example engagement 2200 of a projection 2202 disposedwithin a receiver 2104. The projection 2202 has an aperture 2204 formedsubstantially in the center. The aperture 2204 may provide flexibilityand deflection of the projection 2202 during securing and releasing byallowing a protrusion 2106 to deflect inward toward aperture 2204.

FIG. 23 shows an example engagement 2300 of a projection 2302 engagedwith two receivers 2308. The projection 2302 includes protrusions 2304engaged in respective receivers 2308 (e.g., two adjacent receivers) ofan engagement surface or the surface of the cover 2306. Another exampleof a projection may be having the projection with a protrusion along oneside as one of the projection 2302 described in the FIG. 23. Theprojection may engage to only one side of the receiver and a secondprojection of the same shape with a different protrusion extends towarda different direction may be placed at a distance for engaging anotherreceiver.

FIG. 24 shows an example embodiment of a projection 2402 engaged with areceiver 2104. The example engagement 2400 includes the projection 2402engaged in a space of the receiver 2104. The projection 2402 disposed inthe receiver 2104 shown in FIG. 24 may be seen in FIG. 19 in uncoupledstate.

FIG. 25 to FIG. 28 shows a projection with various centers that makesout of a different material or a combination of materials. The center orcore may be composed of different materials to account for the rigidityof the projection and ease of the projection to engage with a receiver.FIG. 25 shows a projection 2500 having rigid material 2504 with asubstantially hollow center portion 2502. As the projection 2500 pressesor engages to a receiver, the projection is compressed toward the centerhollow portion 2502. The projection may be decompressed to engage to thereceiver in a secure manner.

FIG. 26 shows a projection 2600 having elastically deformable material2602. FIG. 27 shows projection 2700 formed from elastically deformablematerial 2602 disposed around rigid material core 2702. As theprojection 2700 presses or engages to a receiver, the projection iscompressed toward the rigid material core 2702. The projection may bedecompressed to engage to the receiver in a secure manner. FIG. 28 showsprojection 2800 formed from elastically deformable material 2602 withrigid material core 2702 having substantially hollow center 2802.

FIGS. 29 and 30 show a secure pin arrangement 2900. The secure pinarrangement 2900 includes a projection 2906 with a substantially hollowcenter 2904 adapted to receive a secure pin 2902. The secure pin 2902may prevent inward deflection of protrusions 2910, thereby preventingremoval of the projection 2906 from the receiver 2908.

FIG. 31 shows a catch arrangement 3100 including a projection 3102having an engagement surface 3104 formed to engage with and a lockingstructure 3108 formed within a receiver 3106. The locking structure maybe a ball bearing installed in the receiver or latch structure that maybe coupled with the engagement surface 3104. The engagement surface 3104may be a concave surface on the projection 3102. The ball bearingstructure may be locked or coupled with the concave surface to securethe projection to the receiver. The engagement surface 3104 may be alocking structure such as a ball bearing or latch and the lockingstructure may be a concave surface. The receiver and the projection maybe coupled to each other vice versa.

FIG. 32 shows a releasable projection 3200 including an accessory 3202configured for alignment with a cover body 3204. The accessory 3202 mayhave a release mechanism 3206 configured for releasable engagementbetween the accessory 3202 and the cover body 3204.

FIGS. 33-35 show actuation of a releasable projection 3200. Thereleasable projection 3200 includes a projections 3302 of the accessory3202 configured for engagement with a receivers 3304 of the cover body3204. The projections 3302 may be transitioned within the receivers 3304by actuation of a release mechanism 3206. Compression of the releasemechanism 3206 transitions the projections 3302 within the receivers3304 from a secured position to an unsecured position (FIG. 34), therebydisengaging the protrusions 3306 from the cover body 3204.

The release mechanism 3206 may include a spring bias 3308 to bias arelease mechanism 3206 to the secured position. In the unsecuredposition (FIG. 34), the accessory 3202 may be decoupled from the coverbody 3204 (FIG. 35). While the biasing element is shown as a spring, itis within the scope of this disclosure to implement other biasingelements including, but not limited to, elastically deformable materialssuch as rubber.

FIGS. 36-39 show a slidable engagement 3600. The slidable engagement3600 for use with a cover 3606 includes a first layer 3604 and a secondlayer 3602. The second layer 3602 includes apertures 3608 formedcorresponding to the receivers 3610 of the first layer 3604. The secondlayer 3602 is slidable relative to the first layer 3604 providingalignment of the apertures 3608 with the corresponding receivers 3610.Transitioning the second layer 3602 to a receiving position (FIG. 37)allows receiving and engagement of one or more projection 3714 of theaccessory 3712 with the receivers 3610.

After engagement, the second layer 3602 is biased toward partialalignment with the apertures 3608 and the receivers 3610 (FIGS. 38 and39), thereby securing the accessory 3712 with the first layer 3604.

FIG. 40 shows a sliding arrangement 4000 having a first layer 4002 andtwo or more second layers 4004. The second layer 4004 may have apertures4006 corresponding to a row or column within matrix of receivers 4008.The apertures 4006 may align with any configuration or pattern of thereceivers beyond a row or column. Each second layer 4004 may betransitioned independent of the other second layer allowing oneaccessory to be coupled/decoupled from the cover 4010 withoutinterrupting the coupling of other accessories in adjacent rows orcolumns of the cover 4010. The second layer 4004 may be operating bycorresponding push buttons 4012 sliding the second layer 4004 relativeto the first layer 4002.

FIGS. 41A and 41B show a lock arrangement 4100 of an accessory 4102including a lock mechanism 4104. The lock mechanism 4104 may berotatable between an unlocked (FIG. 41A) and a locked position (FIG.41B). The unlocked position may allow compression of the lock mechanism4104, thereby allowing the accessory 4102 to decouple from the coverbody 4106. The locked position may prevent compression of the lockmechanism 4104, thereby preventing coupling or decoupling of theaccessory 4102 from the cover body 4106.

FIGS. 42-45 show rotatable an engagement mechanism 4200 configured toengage an accessory 4202 with a cover body 4206. The rotatableengagement mechanism 4200 includes a rotatable lock mechanism 4204transitionable between a secured position and a released position. Asmay be appreciated in FIG. 43, the rotatable engagement mechanism 4200may have one or more apertures 4304 formed in the cover body 4206 andaligned with one or more receiver 4306. The receiver 4306 is configuredto receive a protrusion 4302 of a projection 4308 in the securedposition (FIG. 43). As may be appreciated in FIG. 44, the rotatableengagement mechanism 4200 may be transitioned to the unsecured position,thereby rotating the protrusion 4302 (shown in FIG. 43) away from thereceiver 4306 and into the accessory 4202 (FIG. 45).

FIGS. 46 and 47 show a projection 4600 for engaging a receiver 4602including a protrusion 4604 and a depressible button 4606. Theprotrusion 4604 is secured within the receiver 4602 unless thedepressible button 4606 is compressed. As may be appreciated in FIG. 47,a lock pin 4702 may be disposed within the depressible button 4606 toprevent compression of the depressible button 4606.
